LibreOffice 6.1.5-3 from the Beowulf repos
and
LibreOffice 6.4.2-2 from Beowulf bpo (back ports)

I managed to get it running off the 64bit iso.
Installed KDE to a SSD. I also installed it to a spinning hd, stock standard xfce4.

I saw errors at the install of grub attempt and the installs were aborted.
I eventually deleted /boot and the efi partition. and re-partitioned the space for /boot , the install went through without a hitch.
That was when I decided to try that process on the Hdd, and it worked as well.

I setup the iwlwifi after boot, installed some other programs and the ssd system is just about where I was.
I usually install proprietary nVidia graphics driver, and steam games. I might do that later.

Thanks for the opportunity, I like Beowulf.

I have read that some newer firmware packages, I personally am using a git clone... that they require a late bios version. Not mentioned here... I hope it helps.

I've come this path to install a wireless card that is not supported in 4.09 kernel, which required me to install backport kernel 4.19.

One other thing, it's my understanding that uuid is most useful for systems that swap hardware frequently, and is better for security (booting).
Otherwise, I have found in a pinch that /dev/sd(x)(n) works fine.

OpenTTD with zbase 32 bit, and Counter Strike through steam... I used to enjoy kpatience(?)

I've just jumped from PcLinuxOs myself, to other non-systemd Os's.
FreeBSD-12 & Devuan-ascii (of course) I'm trialing artix64 on my asus R550() laptop , using openrc.
